Description

Technical Field

[0001] The invention relates to the technical field of drainage systems, and in particular to an anti-clogging floor drain and a control method thereof. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. It can maintain normal drainage in the room and prevent odor from returning to the room. The performance of the floor drain directly affects the indoor air quality.

[0003] In daily life, the floor drain panel in the bathroom is easily blocked by hair, which causes the water on the floor to drain slowly. When the hair is attached to the floor drain panel, the user often needs to clean it manually, which is inconvenient and unhygienic because the hair is thin. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide an anti-clogging floor drain. The first technical problem to be solved by the present invention is: how to effectively prevent the floor drain from being clogged by hair.

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a control method. The second technical problem to be solved by the present invention is: how to prevent hair from adhering to the floor drain.

[0006] The first object of the present invention can be achieved through the following technical scheme: a blockage-proof floor drain, comprising a main body, a cutting mechanism and a power generation mechanism, the main body having a water inlet groove and a drainage channel connected to the water inlet groove, the cutting mechanism being arranged in the main body, the water on the ground can pass through the cutting mechanism into the drainage channel, and the cutting mechanism can cut off the hair hooked on itself; the power generation mechanism is arranged at the water outlet end of the pipe and is electrically connected to the cutting mechanism, and the power generation mechanism can supply power to the cutting mechanism.

[0007] Through the above technical solution, the main body is installed on the ground, so that the drainage channel is connected with the underground pre-buried sewer pipe. The accumulated water on the ground enters the drainage channel after passing through the cutting mechanism from the water inlet trough, and the hair mixed in the accumulated water is hooked by the cutting mechanism; the user turns on the water-using equipment (faucet, shower, nozzle, etc.), and the water flow in the tap water pipe drives the power generation mechanism to generate electricity and supply the cutting mechanism. After the cutting mechanism obtains electric energy, the cutting mechanism starts to operate and cuts off the hair hooked on itself. The cut-off hair smoothly enters the sewer pipe and is discharged through the sewer pipe, thereby effectively preventing the floor drain from being blocked by hair; moreover, the electric energy required for the floor drain is only provided by the power generation mechanism, and no additional electric energy of the user is required, which is green and environmentally friendly.

[0008] Preferably, the cutting mechanism includes a positioning frame, an actuator and a controller, the positioning frame is arranged in the main body, the actuator is arranged in the positioning frame, and the actuator can cut off the hair; the controller is arranged in the positioning frame and is electrically connected to the power generation mechanism, and the controller can control the actuator to run or stop.

[0009] Through the above technical solution, the controller controls the power generation mechanism to supply power to the execution component, so that the execution component operates and cuts off the hair hooked by itself.

[0010] Preferably, the actuator includes a movable plate and a driving member, the movable plate is slidably connected in the positioning frame, and the movable plate has a plurality of shearing teeth 1, the positioning frame is provided with a plurality of shearing teeth 2 adapted to the shearing teeth 1, the shearing teeth 2 are in abutment with the shearing teeth 1, and the shearing teeth 2 can hook hair; the driving member is arranged on the positioning frame and electrically connected to the controller, the output end of the driving member is connected to the movable plate, and the driving member can drive the movable plate to slide back and forth.

[0011] Through the above technical solution, the controller controls the operation of the driving member so that the movable plate completes reciprocating sliding, the first shearing tooth moves with the movable plate, and the hair hooked on the second shearing tooth is cut off by the cooperation of the first shearing tooth and the second shearing tooth.

[0012] Preferably, a reduction assembly and an output rod are provided at the output end of the driving member, the output end of the driving member is connected to the output rod via the reduction assembly, and the driving member can drive the output rod to rotate, and the output rod is threadedly connected to the movable plate.

[0013] Through the above technical solution, the output end of the driving member is decelerated by the deceleration assembly and the power is transmitted to the output rod. Since the output rod is threadedly connected to the movable plate, the rotating output rod can drive the movable plate to slide; the controller controls the driving member to rotate forward or reverse, so as to realize the reciprocating sliding of the movable plate.

[0014] Preferably, there is a clearance gap between two adjacent shear teeth, and the clearance gap is connected to the water inlet groove; a through hole connected to the drainage channel is opened at the lower end of the positioning frame, and the through hole is connected to the clearance gap.

[0015] Through the above technical solution, the accumulated water on the ground can easily enter the drainage channel through the water inlet groove, the clearance gap and the through hole, and the hair mixed in the accumulated water is intercepted and hooked by the second shearing teeth.

[0016] Preferably, the positioning frame has a guide column, the movable plate is slidably connected to the guide column, a preload spring is provided between the movable plate and the positioning frame, and the preload spring can apply a preload force to the movable plate in two directions of the shearing teeth.

[0017] Through the above technical solution, the movable plate slides along the length direction of the guide column, ensuring that the first and second shear teeth will not be misaligned, thereby ensuring the hair cutting effect; the preloaded spring can effectively ensure the stability of the movable plate during the sliding process.

[0018] Preferably, a mounting groove adapted to the lower end of the positioning frame is provided in the water inlet groove, and the mounting groove can limit the positioning frame.

[0019] Through the above technical solution, the installation groove limits the circumferential position of the positioning frame, thereby ensuring the relative position of the positioning frame in the body and further ensuring the working stability of the movable plate.

[0020] Preferably, a sensor is provided on a side of the positioning frame away from the drainage channel, and the sensor is electrically connected to the controller; a float is movably provided on the positioning frame, and the float can float close to or away from the sensor with the liquid surface; after the sensor detects the float, the controller controls the power generation mechanism to supply power to the actuator, so that the actuator operates.

[0021] Through the above technical solution, more hair accumulates in the water inlet tank, which will lead to less water flow passing through the positioning frame. However, if the water flow entering the water inlet tank does not decrease, the liquid level in the water inlet tank will increase. When the float floats up to the liquid surface and is detected by the sensor, it means that there are more hairs in the water inlet tank. The controller directly controls the power generation mechanism to power the actuator, so that the actuator works and cuts off the hair.

[0022] Preferably, the power generation mechanism includes a power generation component and a power storage element, the power generation component is arranged at the water outlet end of the pipeline, the water flow flowing at the water outlet end of the pipeline can drive the power generation component to generate electrical energy, the power generation component is electrically connected to the power storage element, and the power storage element can store the electrical energy generated by the power generation component; the power storage element is electrically connected to the controller.

[0023] Through the above technical solution, after the water outlet end of the pipeline is opened, the flowing water can drive the power generation component to generate electricity, and the energy storage element collects the electric energy generated by the power generation component; and the controller controls the energy storage element to discharge or disconnect the actuator component.

[0024] The second object of the present invention can be achieved by the following technical solution: a control method, the control method comprising the following steps:

[0025] S1. After the water outlet of the pipeline is opened, the flowing water drives the power generation component to generate electrical energy, and the electrical energy is stored in the power storage element;

[0026] S2, after the electricity in the electricity storage element is stored to a predetermined value W1, the controller controls the electricity storage element to supply power to the driving member, and the driving member operates and drives the movable plate to slide back and forth;

[0027] S3. When the amount of electricity in the energy storage element is lower than a predetermined value W2, the controller disconnects the driving element from the energy storage element, the driving element stops running, and the movable plate stops at the current position.

[0028] Through the above technical solution, after the water outlet of the tap water pipe is opened, the water in the pipe flows outward, and the flowing water can drive the power generation component to generate electricity, and the electricity is stored in the energy storage element; after the electricity in the energy storage element is stored to a predetermined value, the controller controls the energy storage element to supply power to the driving part, and the energized driving part drives the movable plate to slide back and forth, thereby cutting off the hair on the second cutting tooth, and effectively preventing the hair from adhering to the floor drain; after the electricity in the energy storage element is discharged or lower than a predetermined value, the controller controls the driving part and the energy storage element to disconnect.

[0029] Preferably, after completing the above step S3, the power generation component stores electrical energy for the power storage element again.

[0030] Through the above technical solution, after the electric energy in the energy storage element is exhausted, the energy storage element will perform the next round of energy storage work, so that the floor drain does not need to consume the user's additional electric energy, saving energy and being environmentally friendly.

[0031] Preferably, the amount of electricity in the power storage element is stored to a predetermined value W1, and after the power storage element supplies power to the driving member again, the movable plate continues to operate from the working position at which it was stopped.

[0032] With the above technical solution, when the driving member is powered on again after power failure, it can continue to work at the previous working position without being reset, thereby increasing the stability of the floor drain operation.

[0033] Preferably, in the above step S1, when the amount of electricity in the energy storage element is less than or equal to a predetermined value W1 and the sensor detects the float, the controller controls the energy storage element to supply power to the driving member, and the driving member operates and drives the movable plate to slide back and forth.

[0034] Through the above technical solution, the sensor detects the float, indicating that there are a lot of hairs in the water inlet tank. Without waiting for the electrical energy in the storage element to be stored to a predetermined value, the storage element is directly controlled to power the drive component, so that the movable plate works in advance, reducing the risk of the floor drain being blocked by attached hair.

[0035] In summary, the beneficial effects of the present invention compared with the prior art are as follows: the hair mixed in the accumulated water on the floor is hooked by the second shearing tooth, and then the first shearing tooth and the second shearing tooth cooperate to cut off the hair, effectively preventing the long hair from clogging the floor drain; the electric energy required for the operation of the cutting mechanism is provided by the power generation mechanism, which saves energy for users and is environmentally friendly; when there are too many hairs attached to the second shearing tooth and the liquid level in the water inlet tank is increased, the controller can control the energy storage element to power the driving part in advance, reducing the risk of the floor drain being blocked by the attached hair; the floor drain works stably and is relatively intelligent.

[0062] Preferably, the actuator 220 includes a movable plate 221 and a driving member 222, the movable plate 221 is slidably connected to the positioning frame 210, and the movable plate 221 has a plurality of circumferentially spaced shearing teeth 2211, each of the shearing teeth 2211 has a shearing edge 2212, the positioning frame 210 is provided with a plurality of shearing teeth 211 adapted to the shearing teeth 2211, and the shearing teeth 211 can hook the hair, the shearing teeth 211 have a shearing edge 2112, the shearing teeth 211 are in contact with the shearing teeth 2211, so that the shearing edge 2212 and the shearing edge 2112 can be staggered and engaged, thereby cutting the hair hooked on the shearing teeth 211; the driving member 222 is arranged on the positioning frame 210 and is electrically connected to the controller 230, the output end of the driving member 222 is connected to the movable plate 221, and the driving member 222 can drive the movable plate 221 to slide back and forth.

[0063] Further, the driving member 222 is preferably a driving motor 2221, and the output end of the driving member 222 is provided with a reduction assembly 400 and an output rod 500, and the output end of the driving member 222 is connected to the output rod 500 through the reduction assembly 400, and the driving member 222 can drive the output rod 500 to rotate, and the output rod 500 is threadedly connected to the movable plate 221.

[0064] The reduction assembly 400 can be a gear reduction commonly used in the prior art, or a reduction form using a worm gear and a worm gear combination, as long as the output torque of the output rod 500 can be increased. Figure 5 , Fig.12 , Fig.13As shown, the driving motor 2221 can be arranged in the middle, lower or upper part of the positioning frame 210, as long as the driving motor 2221 can drive the movable plate 221 to slide.

[0065] Furthermore, there is a clearance gap 2111 between two adjacent shear teeth 211 for accumulated water to pass through, and the clearance gap 2111 is connected to the water inlet trough 110; a through hole 212 connected to the drainage channel 120 is opened at the lower end of the positioning frame 210, and the through hole 212 is connected to the clearance gap 2111.

[0066] The positioning frame 210 has a guide column 213, and the movable plate 221 is slidably connected to the guide column 213. A preload spring 214 is provided between the movable plate 221 and the positioning frame 210, and the preload spring 214 can apply a preload force to the movable plate 221 in the direction of the shearing tooth 211. Preferably, the preload spring 214 is sleeved on the outside of the guide column 213, so as to ensure the fixation of the relative position of the preload spring 214.

The float 216 can float or sink with the liquid surface, thereby approaching or moving away from the sensor 215. After the sensor 215 detects the float 216, the controller 230 controls the power generation mechanism 300 to supply power to the driving member 222, so that the driving member 222 drives the movable plate 221 to work.

[0068] The power generation mechanism 300 includes a power generation component 310 and a power storage element 320. The power generation component 310 is arranged at the water outlet end of the pipeline. The water flow at the water outlet end of the pipeline can drive the power generation component 310 to generate electrical energy. The power generation component 310 is electrically connected to the power storage element 320, and the power storage element 320 can store the electrical energy generated by the power generation component 310; the power storage element 320 is electrically connected to the controller 230, and the power storage element 320 can be a supercapacitor commonly used in the prior art, or an electronic component with power storage function such as a lithium battery.

[0069] Specifically, the power generation component 310 can be a common water flow generator in the prior art, or a hydraulic generator disclosed in the announcement number: CN207513735U, which can generate electrical energy by utilizing the water flowing at the water outlet.

[0070] Working principle of an anti-clogging floor drain:

[0071] The local drain is installed on the ground, so that the drainage channel 120 is connected with the underground pre-buried sewer pipe, and the ground water enters the drainage channel 120 from the water inlet groove 110, the clearance gap 2111, and the through hole 212, and the hair mixed in the accumulated water is hooked by the second shearing teeth 211;

[0072] When the user turns on the water-using equipment (faucet, shower head, nozzle, angle valve, etc.), the water flow from the tap water pipe toward the water-using equipment drives the power generation component 310 to generate electricity, and the electric energy is stored in the energy storage element 320. The controller 230 controls the sensor 215 to be connected to the energy storage element 320. After the energy storage element 320 stores enough electric energy, the controller 230 controls the energy storage element 320 to discharge the driving component 222.

[0073] After the driving member 222 is powered, the driving member 222 starts to operate: the controller 230 controls the driving member 222 to rotate forward, so that the output rod 500 rotates and drives the movable plate 221 to slide downward, and the shearing edge 1 2212 on the shearing tooth 1 2211 cooperates with the shearing edge 2112 on the shearing tooth 211 to cut the hair at the shearing tooth 211, and the output rod 500 stops after rotating forward for a predetermined number of times, and the movable plate 221 is at the lowest point of the sliding stroke; then the controller 230 controls the driving member 222 to rotate reversely, and the output rod 500 drives the movable plate 221 to slide upward, and at the same time, the preload spring 214 is compressed by the movable plate 221 that moves upward, and the output rod 500 stops after rotating reversely for a predetermined number of times, and the movable plate 221 is at the highest point of the sliding stroke, and the reset of the movable plate 221 is completed;

[0074] Then the controller 230 controls the driving member 222 to rotate forward again, so that the cutting tooth 1 2211 cooperates with the cutting tooth 2 211 to complete the cutting of the residual hair from last time. The cut hair enters the sewer pipe with the accumulated water and is discharged through the sewer. The multiple shearing of the movable plate 221 ensures that there will be no residual hair on the cutting tooth 2 211.

[0075] After multiple shearing, if the power of the energy storage element 320 is lower than a predetermined value, the controller 230 controls the energy storage element 320 to be disconnected from the driving member 222 , and the power generation component 310 recharges the energy storage element 320 .

[0076] Too much hair accumulates in the water inlet tank 110, making it difficult for water on the floor to pass through the clearance gap 2111, causing water to accumulate in the water inlet tank 110 and the liquid level to rise. The float 216 floats with the rising water level until it is detected by the sensor 215, and the sensor 215 sends an electrical signal to the controller 230. The controller 230 directly controls the power storage element 320 to supply power to the driving member 222. Regardless of whether the power storage element 320 has reached a predetermined value of electricity at this time, the driving member 222 and the movable plate 221 are operated in advance, and the hair is cut off in time, thereby reducing the amount of hair in the water inlet tank 110 and preventing the floor drain from being blocked by hair.

[0077] The electric energy required for local leakage is all provided by the power generation mechanism 300, and no additional electric energy of the user is consumed, which saves energy and is environmentally friendly.

[0078] A control method such as Fig.16 As shown, the following steps are included:

[0079] S1. After the water outlet of the tap water pipe is opened, the flowing water drives the power generation component 310 to generate electric energy, and the electric energy is stored in the electric storage element 320;

[0080] S2, after the electricity in the power storage element 320 is stored to a predetermined value W1, the controller 230 controls the power storage element 320 to supply power to the driving member 222, and the driving member 222 operates and drives the movable plate 221 to slide back and forth;

[0081] S3. When the amount of electricity in the power storage element 320 is lower than the predetermined value W2, the controller 230 disconnects the driving element 222 from the power storage element 320, the driving element 222 stops running, and the movable plate 221 stops at the current position.

[0082] It should be noted that W1 may be the maximum value of the amount of electricity that the electricity storage element 320 can store, and W1>W2, W2≥0.

[0083] Furthermore, after completing the above step S3, the power generation component 310 stores electrical energy for the power storage element 320 again.

[0084] After the power storage element 320 stores the power to the predetermined value W1 and the power storage element 320 supplies power to the driving member 222 again, the movable plate 221 continues to operate from the working position when it stopped. As another solution, the driving member 222 can also first drive the movable plate 221 to reset, and then continue to cut the hair.

[0085] In addition, when the amount of electricity in the power storage element 320 is less than or equal to the predetermined value W1 and the sensor 215 detects the float 216, the controller 230 controls the power storage element 320 to supply power to the driving member 222, so that the driving member 222 runs in advance and drives the movable plate 221 to slide back and forth.
